Electrodeposition of Silver Particles on an ITO Substrate in Room Temperature Ionic Liquids (RTILs) of 1-Ethyl-3-Methylimidazolium Tetrafluoroborate (EMIBF_4)

摘要

In room temperature ionic liquids (RTILs) of 1-ethyl-3-methylimidazolium tetrafluoroborate (EMIBF_4), for the first time, silver ( Ag) particles were successfully electrodeposited onto an indium tin oxide (ITO)-coated glass substrate by galvanostat and cyclic voltammetrE (CV) methods, respectively. The obtained scanning electron microscopy (SEM) images not only demonstrated that silver particles were fabricated on the ITO substrate, but also indicated that the applied current density is the main factor affecting the morphologies of silver particles prepared by the galvanostat method. Subsequently, the obtained cyclic voltammograms (CVs) indicated that the electrodeposition mechanism of Ag particles on the ITO substrate is different from that on the Ag-coated ITO substrate, as was also discussed by chronoamperometry based on the previously developed nucleation mode. Presenting the generation of sliver particles onto an ITO substrate in RTILs is the main contribution of this paper.
